To a solution of 6-chloro-1H-pyrazolo[4,3-c]pyridine (2.00 g, 13.1 mmol) and DIPEA (3 mL) in DCM (10 mL) was added SEMCl (3 mL). The mixture was stirred at 30° C. for 20 hours. The reaction mixture was concentrated under reduced pressure. The residue was purified by silica gel chromatography using EtOAc/Petroleum Ether (10%˜60%) as eluting solvents to afford 6-chloro-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrazolo[4,3-c]pyridine as colorless oil (3.44 g, 93%). MS (ESI) m/z: 284 [M+H]+.
